Windows 2000 makes it really easy to enter Unicode characters from other languages using IMEs (input method editors) and the on-screen keyboard. You can use these features to test your programs and make sure they will work on other languages of Windows and with the full range of available Unicode characters. You can test with multiple languages by following a few steps:

1. Enable the system to read and write files in the languages you want to test with.
2. Enable keyboard layouts for the languages you want to test with.
3. Change your dialogs to use a new system font, MS Shell Dlg 2.
4. Enter characters into your app using the new keyboard layouts or the Charmap program.

Note that you must have a Unicode build of your app. If you try this with an ANSI build, you can only enter characters that are in the code page of the language of your OS. If you try entering other characters, they will either show up as question marks, or different letters that are missing diacritics.

Enabling foreign languages

The first thing to do is configure the system to read and write files in other languages. Log in as an administrator and open the Regional Options control panel. At the bottom of the first page, there is a checklist box with a list of languages, as shown here.

Check all the languages that you want to test with. For this example, check Japanese and Vietnamese, and click OK. Windows will install fonts, IMEs, and other necessary files and then reboot.

Adding foreign-language keyboard layouts

After the reboot, open the Keyboard control panel and click the Input Locales tab. Click the Add button and then pick a language in the Input Locale combo box. For this example, choose Japanese. The IME combo box should show "Japanese Input System (MS-IME 2000)" as shown here:

Click OK. Click Add again and select Vietnamese, then click OK. Your Keyboard property sheet should look like this:

Click OK to save your changes. There should now be a language indicator icon in the tray, which will show the native language of the OS (for example, "EN" if you're using English Windows). Pressing Left Alt+Shift rotates your keyboard language among the languages you set in the Keyboard control panel. You can also left-click the language indicator to get a menu of all the installed languages.

Changing dialog fonts

Now that the system is set up to let you enter foreign-language characters, you need to tweak your dialogs so they can display the characters. Windows 2000 has a new system font name, MS Shell Dlg 2. This is not a real font, but rather a special name the system recognizes. When a dialog is created with this font, the system substitutes a font that is capable of displaying characters in all of the installed languages. (You can read about Windows NT font substitution in MSDN under Platform SDK\Windows Base Services\International Features\National Language Support\About National Language Support\Localization and the Shell Font.) By default this font is Tahoma. Once you set your dialogs to use this font, they will automatically be able to display any Unicode character from any installed language. Note that you'll need to edit your .RC files by hand, since you can't set the font to MS Shell Dlg 2 through the MSVC dialog editor.

Entering foreign-language characters

If you change the keyboard language to Japanese, you'll see the IME in the lower-right corner. Using the IME requires knowledge of Japanese to enter correct syllables (and teaching Japanese is a little beyond the scope of this article), so for the purposes of testing you can use Charmap to enter Japanese characters.

To run Charmap, click Start, point to Programs, point to Accessories, point to System Tools, and click Character Map. Select either the MS Mincho or MS Gothic font, and scroll the character list down until you see the Japanese characters. Double-clicking any character adds it to the edit box at the bottom of the window, and clicking Copy puts all the characters in the edit box onto the Clipboard. Here is what Charmap looks like after double-clicking three characters:

After copying the characters to the Clipboard, you can them paste them into any input field in your program.

Another way to enter characters is by using the on-screen keyboard, a new Accessibility feature in Windows 2000. The on-screen keyboard lets you click buttons with your mouse, instead of hunting for keys on the keyboard. To open the on-screen keyboard, click Start, point to Programs, point to Accessories, point to Accessibility, and click On-Screen Keyboard. The Vietnamese keyboard is shown here:

Other languages will differ, naturally, in the placement of some letters. For Vietnamese, the top row of keys enters diacritics and accented letters, as well as the two keys between P and backslash. To add a diacritic to a vowel, type the vowel and then the diacritic. For example, to enter the name Nguyen, type "Nguy" as normal letters. To enter the e (which has both a circumflex and a tilde), press the 3 key (for ê) and then press the 7 key to add the tilde.

When you want to use the on-screen keyboard, click in the window that you want to receive the keystrokes, and then click in the on-screen keyboard window. When you click buttons on the keyboard, the keystrokes will be sent to the window with the focus.

The text would be Khmer alone or a string having both English and Khmer. I can notice that Office applications display text in Khmer script correctly. We want to do the same in our application too. Right now it shows Khmer script as boxes. Is there a solution for this? If anybody has any possible solution for this problem, please guide us in this regard.

Michael Dunn 6:26 27 Sep '05   Not sure what you mean by "DOS prompt do not support foreign language characters". Filenames are stored in Unicode, so if you have the language support and its fonts installed (from the Regional ctrl panel applet) then the display will work (as long as you use a font like Tahoma that contains the characters - do not use MS Sans Serif). --Mike-- Visual C++ MVP LINKS~!

Michael Dunn 13:21 13 Nov '05   The process for dialogs is: Change DIALOG to DIALOGEX in the .rc file Change the font name to "MS Shell Dlg" Add the DS_SHELLFONT style Now keep in mind that you need to be using a font that contains all those glyphs. Tahoma should contain the common languages (at least the 30 or so that the OS is localized into). --Mike-- Visual C++ MVP LINKS~! Ericahist | 1ClickPicGrabber | NEW~!

Any help will be appreciated Thanks Alex Sign In·View Thread·PermaLink 1.00/5 xilli I am facing a similar problem Zephyr_BP 3:52 27 Dec '04   Hi All, I found that caret movement in a rich edit box (1.0) when containing Japanese text is erratic. On investigation found that "normal" SendMessage messages like "EM_POSFROMCHAR" and "EM_LINEINDEX" are returning improper values. The whole setup works OK when English text is used. I found that the Japanese text being displayed in the rich edit control are not composed of a single character (i.e DBCS). But does it automatically follow that rich edit control (1.0) will not be able to follow the exact caret movement style? Has anyone any idea about what exactly is going wrong?

For beeing compatible with Windows 9x it is better to use "MS Shell Dlg" with the DS_SHELLFONT (this is DS_SETFONT | DS_FIXEDSYS) This flag will use "MS Shell Dlg 2" in Windows 2000/XP See http://msdn.microsoft.com/library/en-us/intl/nls_4qcn.asp[^] Also you have to make sure, that you use DIALOGEX resources.
